ok, no one else seems to be using this forum anymore so here's a couple more things. i put dual fans on the radiator, no shroud. these fans flow 3000 cfm each, which my one single fan flowed that much. now when i come to a stop the temp rises quickly, and its hard to keep down. this morning it was absoluetly fine, it stayed 10 degrees colder then the single fan. i know that mean im not flowing enough air through the radiator, but im covering more of the radiator now! and also, my valve cover breathers are smoking, even after i've driven for a while. i touched the radiator while the car was running, the front was cold, and there was really hot air being pulled from the fans on the backside. dunno if that makes a difference or not.
